Device for melt spinning, treating and winding synthetic threads

Abstract

A device for melt spinning, treating and winding synthetic threads includes a spinning unit, a treatment unit and a winding unit. The spinning unit, the treatment unit and the winding unit are arranged in tiers one above the other and form a plurality of single-thread or multi-thread production positions along the longitudinal side of a machine. To permit a rapid, simple operation, in particular at the start of a process and during interruptions of the process, an operator walkway is located at a height between the treatment device and the winding device.

1. A device for melt spinning, treating and winding synthetic threads, comprising:
 a spinning device, a treatment device, and a winding device arranged on top of each other in stages, and which are arranged at a plurality of single thread or multiple thread production positions along a longitudinal side of the machine, and 
 an operating platform to provide access to the production positions, the operating platform being arranged at the longitudinal side of the machine at a height between the treatment device and the winding device and including one passage opening per production position opposite the winding device, 
 wherein the winding device has, per production position, at least one winding position comprising two spool spindles, which are alternately held in an operating position for winding the spool, and auxiliary devices for spool changing, and wherein a movable thread guide is associated with each winding position, which thread guide is constructed and arranged to be guided back and forth between an operating position adjacent to the passage opening of the operating platform and a feed position adjacent to the spool spindles. 
 
     
     
       2. The device according to  claim 1 , wherein the thread guide is formed by a deflection means that is held at a guide carriage in a height adjustable manner. 
     
     
       3. The device according to  claim 1 , wherein the auxiliary devices of the winding position have a pivoting feed arm constructed and arranged to be guided at a guide end in the straight grain held in the feed position by means of the thread guide for the deflection of the thread. 
     
     
       4. The device according to  claim 1 , wherein a doffing device is associated with the winding positions for removal and transport of the spools. 
     
     
       5. The device according to  claim 1 , wherein the winding positions of adjacent production positions are constructed and arranged to be driven and controlled independently of each other. 
     
     
       6. The device according to  claim 1 , wherein the treatment device has multiple godets per production position for stretching one of the threads, which are constructed and arranged to be driven and controlled independently by the adjacent production position. 
     
     
       7. The device according to  claim 6 , wherein the godets of the production positions are mutually held at a frame wall, which has a feed device constructed and arranged to support additional treatment units. 
     
     
       8. The device according to  claim 7 , wherein the additional treatment units per production position are formed by a texturizing nozzle and a cooling drum.
